how expire password automatically
I have a couple of questions regarding the passwords and security:
1. How do I make all the passwords expire within, say 60 days of previous time the password was reset? Do I need to run a script for it or can we acheive this using commands?
2. I want to prevent some users in my system from executing 'su', while others should be able to do it. How do I acheive this? I read online that adding those some users to a group and chmod the group permissions is not a good idea... I was thinking if there was a better way to do it.
I am runnning Redhat Enterprise 3.... Please advice...
